You should all know by now that Mercedes is bringing back the twin turbo V12 with the new R231 SL65 AMG. We originally thought this was just the same old M275 V12 that had seen duty in the previous generation 600 and 65 AMG's but the motor has received some updates along with a new M279 engine designation. The 6.0 liter V12 to reach its new 630 horsepower rating received far more than just different ECU software.

A multi-spark ignition with twelve double ignition coils is used that Mercedes states provides for a smoother motor and more effective combustion. This also is used in conjunction with a new engine management system.

The cylinder heads were also revised in order to flow better for more power. The turbos have been changed featuring new wheels and are mated to new manifolds. The wastegate ducts have also been revised.

Additionally, the exhaust system underwent some significant changes. The catalytic converter system was optimized both for emissions and power. The wall thickness of the exhaust was reduced and the system is now 7 pounds lighter than the previous generation.

Other parts such as the intercooler, throttle body, and airbox remain the same. The M279 is a nice update to what already was a stout powerplant.

Are you retarded or something ? I know someone in Affalterbach who has been at the Performance Studio since 2006. That's my source - but what does it matter ?? You agreed to the bet already so there's no backing out now. When the SLS BS comes out I'll be looking for my $10g's.
And what makes you think it will be a MY2013?

looool. Right you are!

All you got is BS

actually you are talking about my 10K. Now how will the loser among us (which is obviously you) will pay up?

You can send me your phone number on PVT and I'll do the same and lets talk about it.
